Good morning, everyone! We’re working on something in a similar space to Dremio, so we’re evaluating it.
Dremio looks like some amazing tech, but I’m primarily concerned with compatibility and documentation. For example, Presto/Drill have Stackoverflow questions, fairly heavy backers, have been around for a while, and are fairly well understood, so I can look up what kinds of queries are supported, troubleshoot, etc.
Dremio, while it has an amazing feature set, seems much more of a black box.
- What kinds of JOINs are supported by the Dremio SQL variant? Compare to Presto’s SQL reference. Is Dremio using Presto?
- If I get an error message, how can I track it through the stack? What is the stack?
So, if I get more information on what the underlying technologies are, we’ll have more confidence that it’s not a black box and we’ll actually be able to debug it, fix bugs, maintain it, etc.
